Gas cover type integrated environment-friendly stove and gas cover smoke exhaust method

Abstract

The invention relates to a gas cover type integrated environment-friendly stove and a gas cover smoke exhaust method which can completely exhaust oil smoke or mixed gas generated in a pan when cooking and frying and harmful gas generated by burning fuel gas. A fluid membrane smoke dust absorbing and exhausting device is formed by stacking a positive-pressure gas ring and a negative-pressure gas bin, wherein the positive-pressure gas ring is positioned on the negative-pressure gas bin, the inner side of the positive-pressure gas ring is annularly provided with fluid outlets or spiral fluid outlets, the inner side of the negative-pressure gas bin is annularly provided with a plurality of fluid suction inlets which are positioned below the annular fluid outlets or the spiral fluid outlets. The invention has the advantages that firstly, the air cover type integrated environment-friendly stove completely covers a pan hole surface by dynamic gas flows and avoids the leakage of oil smoke andgas in the pan and harmful gas generated when a gas stove is burnt; secondly, because a fluid membrane smoke dust absorbing and exhausting device cavity is in a big end down horn shape, the gas covertype integrated environment-friendly stove not only can stop oil smoke and gas to flow upwards, but also can reduce power needed by negative-pressure suction gas, has obvious energy saving effect andhas no smoke, oil and harmful gas when being used for cooking and frying.

Description

technical field [0001] The invention relates to a gas hood integrated environment-friendly stove and a gas hood smoke exhaust method that can completely discharge the cooking fume or mixed gas generated in the pot and the harmful gas generated by gas combustion when cooking and cooking. Manufacture of hood-type integrated environmental protection stoves. Background technique [0002] Patent No. 00134172.3, titled "A Fluid Diaphragm Suction and Dust Exhaust Device", the device is provided with a pressurized fluid outlet parallel to the diffusion surface on the side of the diffusion surface of the smoke pollution source, and the outlet is connected to a pressure fluid source. On the other side of the symmetry, there is a negative pressure fluid suction port parallel to the diffusion surface, and the suction port is connected to a negative pressure generating device; the fluid blown out from the blowing port enters the suction port to form a fluid diaphragm, which diffuses the ...

AI Technical Summary

Problems solved by technology

Its shortcomings: First, because the positive pressure air outlet is opposite to the negative pressure air inlet, it is impossible to form a full-coverage positive pressure airflow cover in a pot plane, resulting in smoke, mixed gas, and gas burning during cooking. The harmful gas generated during the operation can not be covered and leaks, which not only has low exhaust efficiency, but also is not environmentally friendly; secondly, because the inner cavity of the fluid diaphragm suction and exhaust device is a straight-line structure, it does not have the function of fluid collection, which is easy Causes the leakage of smoke, mixed gas, and harmful gases produced during gas combustion

Its shortcomings: First, because the positive pressure is blown as the lower arc air outlet, and the negative pressure inferior arc air outlet is theoretically forced to be too concave arc relative to the air flow channel, but in practice it is not only difficult to achieve, but also extremely large. The suction power with increased negative pressure is noisy, and more importantly, it cannot form a full-coverage positive pressure airflow hood in a concave pot plane, which also causes smoke, mixed gas, and gas combustion when cooking and cooking The leakage of harmful gas is not only low in efficiency, but also not environmentally friendly; second, because the inner cavity of the fluid-enveloping surface-type powder and smoke shielding and separation discharge device is a straight-line structure, it does not have the function of fluid collection, and it is also easy to cause smoke. Leakage of gas, mixed gas, and harmful gases produced during gas combustion

[0006] The deficiencies in the above two patent applications: First, because the positive pressure air outlet is opposite to the negative pressure air inlet, it is impossible to form a fully covered positive pressure airflow cover in a pot plane, resulting in smoke when cooking. , mixed gas, and harmful gas generated during gas combustion can not be covered, resulting in leakage, which not only has low exhaust efficiency, but is also not environmentally friendly; With the function of fluid gathering, it is easy to cause the leakage of smoke, mixed gas, and harmful gas produced during gas combustion
